when the operation of the shaping machine is discontinued.

The ware transferring mechanism shown herein is of the class sometimescalled a take-out", being specially adapted for taking the finished wareout of the molds of a glass shaping machine. lt is herein shownassociated with a glass shaping machine, which is constructed andoperated substantially like that. disclosed in Patent No. 1,316,550 andis designed to be operatively connected with certain of the dr.iving andcontrolling elements of that machine in order to function in synchronismtherewith.

The machine o1 the patent referred to is a duplex machine having moldtables disposed in right and left-hand relation to each other andadapted to receive in alternation mold charges delivered from a singleglass feeding device. In the patentreferred to, the right-handmachine ofsuch a pair of associated shaping machines was selected for specificillustration and description, but

'in the present instance, a take-out mechanism o the present inventionis shown as being adapted to the left-handmachine of such an oranization. lIt will be understood, however, tiat a ri lit-hand take-outmechanism embodying tie present invention may be utilized in connectionwith a right-hand shaping machine by the reversal of its parts.

This left-hand machine has a mold table `1, shown by dotted lines inFig. 1, mounted for intermittent rotation on a vertical spindle 2, andcarries a plurality of divided molds, the halves 3 of which are hingedupon pins 4` secured to the table 1. (Figs. 2 and 11). Each mold isopened and closed by a slide 5, which is connected to the mold halves bya suitable link connection, the actuatin'g mechanism of which will bepresently described. Each mold is provided with a bottom plate 6,carried by a vertical stem 7 which extends through the table and isslidably mounted in a suitable bearing 8.

The mold table is rotated by shaft 9 (Fig. 1) provided with a worm.v 10which meshes with a worm gear 11 fixed to a shaft 12. The shaft 12 isprovided with cams 13 and 14 which respectively actuate arms 15 and 16of a bell crank lever 17 which is pivotally mounted on a shaft 18. Theshaft 18 is carried by a bracket 19 secured -to-a. stationary portion ofthe shaping machine, not shown. The cams 13 and 14 thus effect apositive partial rotation of the table, and

pivoted upon the spindle 2,\and carries a spring pressed rotator'bolt 23which periodically engages successive notches 24 in a ring 25 on theunder-side of the-table v1, and intermittently advances the table andthe molds carried thereby. The ring 25 is'provided with eight suchnotches, the table being adapt-ed for eight molds.

The rotator bolt 23 is moved radially in the arm 22 to successivelyengage and dis-l engage the notches 24 by means of the followingdescribed mechanism: On the drive shaft 9 is a worm 26 which drives a.worm gear 27 lixed to a vertical shaft 28. A cam 29 fixed to the upperend oi the shaft 28 acts against a roller 30 carried by an arm 31 ofa'bellcrank lever 32 which is pivotally mounted at 32a upon a fixedportion of the machine, not shown. The arm 31 has an arcuate track 33engaging a roller 34 on the rotator bolt 23. During the time that therotator bolt 23 is in engagement with` one of the notches 24, whileadvancing Vthe table, the cam 29 permits the arm 31 to be held outwardlyunder the action of the spring pressed rotator bolt 23 and the rollercarried thereby. Then the arm 22 and the bolt 23 reach the end of theiractive stroke, l

the cam 29 bears against the roller 30, swinging the arm 31 ot' thelever 32 inwardly. The a1'1n31 engages the roller 34 and forces therotator bolt 23 radially inwards and out of the notch 24 with which itis, at such time, in engagement (Fig. 1). When the arm `31 is in thisposition the arcuate. track 33 is oncentrie with the path of travel ofthe roller 34 and maintains the rotator bolt 23 in a retracted positionduring 'its return movement, which ceaseswhen the rotator bolt 23 is inalignment with the next succeeding notch 24. At this stage the cam 29releases the arm 31 which in turn releases the rotator bolt and permitsit to move radially linto engagement with thc notch for the nextadvancement ofthe table.

To prevent the table from rotating while the rotator bolt is ,disengagedfrom the ring 25. a suitable locking mechanism is pro vided,consistingof a spring pressed lock bolt 35 mounted in a guide 36 carriedby a stationary' portion of t-he machine, not shown. This bolt is solocatedthat a notch 24 of the table is brought into alignment therewithwhen the table completes each forwardwmovement, at which position thelock bolt 35 is pressed by its spring into the notch 24 and locks thetable duringthe return stroke of the rotator arm 22. The lock bolt 35 iswithdrawn from the notch 24 bymeans of a lever 37 on a fixed stud 38 andhas a slotted end engaging with a pin 39 on the lock bolt. An arm 40 isfixed to the lever 37 and is provided with a cam roll 41 for engagementwith a cam 42 which is fixed to the vertical shaft 28. The lock bolt cam42 and the rotator cam 29 areso set that when the latter withdraws therotator' bolt 23 from a notch 24, at the end of its forward stroke, thecam 42 will allo`w the lock bolt 35 to enter a succeeding notch fromitsnotch 24, thus releasing the table for its forward movement.

'The rotator bolt 23- may be manually Withdrawn from the table and heldout by means of a treadlev 43, pivotally mounted in a bracket 44 on thebase of the machine, lvand providedjwithan upwardly extending army 4 51which is pivotally connected to an arm 46 of the lever 32 by means of alink 47. By reason of this connection, the treadle 43 oscillatescontinuously during. the normal operation vof the machine but if it isdesired ,at-any time to stop the shaping machine, it

is only `necessary to maintain the treadle in a depressed position inorder to hold the bolt .23 out of engagement with the table.

. It -is sometimes desirable to .rotate the table ofthe shaping machineby hand during an inoperativeperiod in order to change the molds or. tomake other adjustments'. and to releasethe table for such movementt thelock bolt 35 may be-retracted and held in a retracted position, by meansof 'a levery 48 (Figs. 1, 19, and 21) which is pivote/d, as at 49,-to afixed portion of the machine,` not shown.v and which is adapted to bearI. against the lock bolt lever 37. The. lever 48 is provided with an arm'50 having a' slot -51 formed therein which, is engaged by a crank pin52 carried by an arm 53 fixedv to a shaft 54 (Fig. 1). The shaft 54 isjournaled in a bearing. 55 carried by the casing of the Waretransferringmechanism` presently to be described, and is provided withan operating handle 56. When it is desired to Withdraw 'or hold out thelock bolt thehandle 56is moved through an arc of 180, thereby swingingthe arm 53 in an upward direct-ion andcausingtlie `lever 48 to forcethel arm 37 about its pivot 38 and withdrawthev i position past its.dead center relative to the action of `the arm 50 (li'igs.` 19 and 21).

The rotator bolt 23 is also locked out of action during such time asthelock bolt 35 is withdrawn, through the medium .of-.a pawl 57 (Fig. 1)which is carried the lever37 and is adapted to enga-ge behind the arm 31ofthe bell crank lever 32. The rotation of the Amold table ofthe shapingmachine may f thus bedis'continued independently of the treadle 43, `forthe vreason. that if the levier 37 vis moved to retract the lock bolt35. the

" pawl 5:7 will be'carried into the path of i movement of the end-loftheiarm31 of the "lever 32,'and will fall behindthatlarm upon the -firstVinward movement of the4 arm 31. v As thus far described, theconstruction of 'the operation of the machine. 75 and 78 arenormallyheld in yieldablethe machine is substantially that disclosed 1nPat-ent 1,316,550 above referred to.

The Ware' transferring mechanism of the present invention is carried bya casing 58 spect `thereto by means of brackets 60 which are fixed tothe side wall of the casing and to the base of the machine (Figs. 9 and10). A vertically extending cam shaft 61 is disposed Within the casing58and mounted in bearings 62and 63, which are respectively carried by thecover 59 and a housing 64 (Figs. 6, 7 and 9). A Worm gear'65 is'rotatably mounted on the shaftl61 vWithin the housing 64 and is drivenby a. worm 66 fixed to a horizontally extending drive shaft 67 (Figs. v5and 6). This shaft is journaled in bearings 68 on the housing 64 andprojects through the side Wall of the casing 58 and its outer end isprovided with a bevel gear 69'4 which is driven by avbevel gear 70 fixedto one end of a transmission shaft 71 (Fig. 1), which is mounted inbearings 72 and is provided at its other end with a bevel gear 73 drivenby a bevel gear 74 fixed to the main drive shaft 9 of the shapingmachine.

A driving vconnection isn effected between the Worm .gear 65 and theshaft 61 by means of a pawl 75 (Fig. 5) carried by the worm gear 65 andadapted to engagea 'shoulder 76 formed in the periphery of a disk 77fixed to the shaft 61. In addition to the pawl 7 5. the Worm gear 65 isprovided with a hold-back pawl 78 which engages a shoulder 79 formed onthe disk 77 and prevents the shaft 6.1 and the 'cams carried therebyfrom running ahead 'of the Worm gear during The pawls engagement 'withthe periphery of the disk -77 by means of a suitable connect-ing spring80. The pavvl 75 is provided With a rear- Wardly extending fingerportion 81, thefunc.- tion` of which will be presently set forth.

The instrumentalities which open the molds, remove the -ware therefromand steady it during its removal, are mounted on vthe, top of the casing58 in the following manner:

A tubular column'82 is mounted on the cover -59 of thecasing 58 andconstitutes a support for inner and' outer concentric rock sleeves'83and 84 respectively. which extend" through the column and into the upperport-ion of the casing 58 (Fig. v7)'. The

sleeve 83 is rocked within the outer'. sleeve 84 by means of an arm 85which is fixed to itsv lower end and which is provided with 'v" arollerfor engagement With a cam c87 ed to the shaft 61. A hub member 88 isfixed to the upper ,end of the sleeve 83 and provides a bearing for an.arm 89. This lao arm is Fixed to the hub 88 by means oit a` removablepin 90 during the normal operation oi' the machine.

The arm 89 is pivotally connected to an arm 9:3 which is fixed to a rockshaft 96 by means of a yieldable connection 97 (Figs. 2 and 4). Theshaft 9G is journaled in bearings which are carried by stationary1portion of the shaping machine. A mold Opening lever 98, provided with acam surt'ace 99. is fixed to the. lower end ot' the shaft 98 and isadapted lo be intermittently moved across the path of travel of a roller100 which is carried b v the mold opening rod Ii. The action ot' thelever 98. is so timed that when a mold comes to rest at the transierstation. the lever 08 swings about its pivot and into engagement. withthe roller 100` thereby ,Forcing the mold :ugtuating rod radiallvinwards to open the mold.

lf tor any reason it should become neces sary to remove ware from themold by hand. such as through a failure of the take-out mechanism tofunction. the molds may be opened by the rotation ot' the mold table bylocking the. lever 98 in a iixed position with the cani surface 99thereoiE in the path of the rollers 100. Vhen the lever 98 oecupies sucha position, the rollers 100 will successively engage the cani surface 99and be forced radially inwards to open the molds at the transfer stationwithout dependingl upon the. oscillation oi the lever 98 tor thispurpose. This is accomplished by transferring the pin 90 to apertures 91and 92 which are respectively provided in the arm 89 and in a. bracket93 carried by the column 82 (Fig. 7). Ry so doing, the arm 89 isdisconnected from the hub 88 and is locked to the bracket 93 in theposition shown in Fig. 2. For convenience the arm 89 may he movedmanually in order to align the apertures 89 and 90 by the use of a leverconsisting' ot a bar or pipe inserted in a. socket 94T, which isprovided for that purpose on the side of the arm (Figs. 2 and Theyieldable connection 97 preferably comprises a rod 101, one end of whichis pivotally connected to the arm 89. The other end ot the rod 101 isslidably disposed in a block 102 which is pivotally connected to the arm95. A coiled spring. 103 surrounds the rod 101 and is disposed betweencollars 104 and 105 which are carried by the rod 101. rl`hisconstruction provides a'connection olI si'lfi'ieient rigidity to meet'with normal operating conditions, but in the event that au abnormalstrain is encountered. such as may be occasioned by a mold refusing toopen. the. movement ol" the lever 98 will cease when it engages theroller of such mold and the rod 101 will slide through the block 102against the pressure of the spring 103. Conversely, if the lever 98 islocked in the path of the rollers 100, by means of The operation o'ftaking out the Ware isA shown diagrammatically in Figs. 12 to 16. lVhen,as here shown` the top of the bottle does not project above the top ofthe mold,

the bottle is pushedup from below by means of an arm 106,\vlii -h isadapted to engage the lower end ot the/stein 7 ot' the mold bottom plate6 and to raise the same (Fig. 9).

The arm is carried by a slide 107 which is mounted in ways 108 providedon a side wall ot' the easing 58. The slide 107 is reciprocatcd in itsways by means of a link 109, the lower end ol which is pivotallyconnected to one end of a lever 110 which is iixed to a rock shaft 111journaled in bearings 112 carried by the casing 58. A lever 11? ismounted for rocking movement on the shaft 111 and is provided with aroller 114 for engagement with a cam 115 iXed to the shaitfl. The levers110 and 113 are yieldably counected'to move in unison during the normaloperation of the machine, by

means of a detent 116 which is slidably mounted on the lever`113 forengagement with ay notch 117 formed in a block 118 carried by the lever110. The detent 116 is maintained in engagement with the notch 117 by aspring 119 which exerts sufiicient pressure to maintain an operativeconnection between these parts under normal operating' conditions butwhich may be compressed sutliciently to permit the detent to be forcedout of itsnotch to render the lever 110 inoperative in thev event thatan abnormal strain is encountered. When the levers 110 and 113 are thusdisconnected the lever 113 will oscillate upon the shaft` 11 Withouttransmitting any motion to the lever 110 and to the parts actuatedthereby.

The mechanism for removing the Ware from a mold subsequent to itsvelevation therefrom by the bottom plate `6, includes a transfer arm 120which is adjustably secured to the upper end of the outerrock sleeve 84(Fig. 7 This arm is recessed on its under side to provide a housing fora carriage or slide 121 which is supported therein by gibs 122 (Figs. 17and 18). A pair of cooperating take-out or transfer tongs 123 areivotally mounted on the slide 121 for horizontal swinging movement, asat 124, and are provided at their outer ends with coacting ware engagingjaw members 125 having a radius of curvature corresponding approximatelyto that of the ware to be transferred, and which are madeinterchangeable to provide for Ware of Vdifferent diameters. The tongs123 are also' provided with inwardly extending arms 126 whichproject'beneath a'plate- 127 carried -by the slide 121, therebypreventing undue strain upon the `pivots 124. The tongs 123 are closedby means of aspring actuated plunger 128 which is slidably mounted in atubular guide 1,29 carried by the slide 121 and bears against a lug 130provided on one contiguous relation -with respectl t0 the lug 130. Thetongs are opened against the member ot the tongs. vThe lug130. engages-Ia similar lug 131 provided on the opposite member of the tongs and4which extends in an opposite direction and in overlapping actionot' theplunger 128 by means of a bell crank lever 132, one arm 133 of whichextends upwardly into engagement lwith the lug 131 and which is mountedon a. shaft 134 carried by the slide-121. The other arm 1 35 of thelever 132 extends rearwardly and is actuated by means hereinafterdescribed.

" The .distance between the jaws 125 when in a closed position. isregulated by an adjusting screw 136 which is threaded into a lug'137'p1ovidedon` the-slide and which is engaged by the arm 133 of thelever 132 whenVv the tongs are closedtby the plunger 128.

' The tongs are oscillated to and from a y position adjacent to thetransfer station by Y by an arm 139 to which it is connected byl meansof an arm 138 (Figs. 7 and 8) which vis fixed t0 the lower end of theouter rock sleeve 84. \This arm is, in turn, oscillated a`l link 140,The arm 139 is pivotally mounted on the casing 58 at 141 and igprovidedwith a'roller 142 for engagement with a cam A143 fixed to the shaft61.-' l

The'slide 121 and the tongs 123 carried Athereby are reciprocated onVthe arm 120 by -means of a cam 144 (Figs..2 and 18) ixed to the column82 and engaged by a roller 145 mounted on the under side. oi the slide121.

l When the..arm.'120 is` swung toward the transfer station the cam 144forces the roller 145 and -the slide 1'21'radially. outwards and'projects the tongs toa position in which the .jaws 125 are directlyoverthe ware. 'Conversely, when the tongs are swung, away from thetransfer' station toa deliverystation, the cam 144, acting onthe roller145,

simultaneously retracts the slide 121 to the position 'shown yin Figs.17 and 18. This retraction yof the slide is for the purpose oi"providing sutlici'ent clearanceforthe'ware as it 1s removed from betweenthemold sections. The tongs are opened to receive and .discharge theware at the transfer and .deliv- .erv stations respectively, by means'ofrods 146 and 147 wlnchare. slidably mounted for verticalunovement inbearings 148 and 149- carried by a housing 150 which is, in turn,mounted on the cover 5.9 of the easing 58 (Fig-9). The rods 146'and 147are so po.

siti'on'ed in the pathoftravel of the tongs opening lever 1 32 thatthehorizontal arm 135y thereof isdisposed directly above one or theother of these rods when the tongs 123 occupy a position at eitherextreme of their Apath ofmovement (Figs."17 and 18).' The rods 146 and147 are simultaneously actuated at these points by means of a lever 151(Fig. 9), which is pivotally mounted' within the housing 1.50, as at152, and which constitutes a common support for these rods. The lever151 is provided with a,l roller y153 which engages a .disk cam 154 fixedto the upper end of the shaft 61.- The movement of these rods is sotimed `with respect to the swing movement of the tongs 123 that when thetongs have been moved to a position above a mold, .the rods 146 and 147are raised and the rod 146 will elevate the arm 135 of the lever 132against the action of the plunger 128 (Figs. 16 and 17) thereby open-A Iing the tongs to` receive the ware. As soon; however, as .thevware isvelevated `and proporly positioned between the. tongs, the rods v146, and147 are lowered, permitting the spring actuated plunger 128 tol closethe tongs about the ware. When theton s have beenswung to the deliverystation t e arin 135 of the,lever 132 occupies a positionin alignmentwith the rod 147 which'is again raised along withA the rod 146 andactuates the lever 132to discharge the ware. It will be noted 4in thisconnection that, althou h both'of' the rods 146. and 147 ascend andetogether, when the rod 146o ens the' which provides sufficientclearance for the I vware as it is withdrawn laterally from between thernold sections. ware'from the molds to the deliveryl station vmay,however, be altered by changing the shape of the cam 144.

Tol-prevent the disl'odgment of the vware/ from the bottom plate 6, bythe openin of the 'mold' or while it is being elevated rom the mold, asteadying in 155 is provided The path of the i which descends` into t eware before the.

mold opensv (Figs. 3, 7'. and 12 to 116), and' raises therewith until itis properly posi- -tioned between the jaws y of the take-out tongs. Thispin, also provides lateral support for ware having imperfect bottomportionsusuch as may result frornincomplete blowing, vand which aretherefore of themselves unable to stand in an upright position.

The pin155 is suspended'from an arm 156.

by meansofa pin157- 7). The pin'157 is replaceable and is preferablymader of a :trangible materialZ such as cast iron or brass, so that ifabnormal strain is brought'to bear upon the steadying pin 155, the pin157 will break without causing other' damage to the machine or to thepin 155. The arm156 is fixed to the upper end ot' a non-rotatable,vertically movable rod 158 which is mounted to slide within the innerrock sleeve 83, being prevented from rotating by means of an arm 159lixed to the lower end of the rod and projects laterally into a verticalguideway 160 on a side wall of the casing 58 (Figs. 7 and 8). The rod158 is reciprocated within the sleeve 83, to raise and lower thesteadying pin 155 in timed relation to the horizontal movement of thetake-out tongs 123, by

.' means of la lever 161 pivotall-y mounted on the casing, at 162, andprovided with a cam roller 163 for engagement with a cam 164 ixed to thesha-tt 61, (Fig. 9). A. cushioned action between the rod 158 and thelever 161 is effected by means o a plunger 165 which is seated in ayrecess in the end of the rod 158 and. is pressed by a spring 166 intoengagement with the lever 161, (Fig. 7). This spring is designed toabsorb the shock in the event that the rod-158 and the parts carriedthereby should lodge or be otherwise held in a raised position andsubsequently dropped upon the lever 161.

The action of the steadying pin with respect to the take-out tongs 123is as iollows: i

Upon the arrival of a mold at the trans-ier station, the steadying pin155 descends into the ware between the jaws 125 before the mold isopened, and rises simultaneously I with the ware when the latter iselevated by the bottom plate 6. As soon as the ware is engaged betweenthe jaws 125, the bottom plate 6 descends, as has been previouslydescribed, the steadying pin continuing its upward movement until it isentirely withdrawn from the ware to a position without i the path of thetongs 123 (Fig. 16), at which vtime the tongs 'are caused to movehorizontally and to deliver the ware to a rotating transfer disk 167(Figs. 2 and 3).

The transfer disk 167 is fixed to a vertically extending shaft 168 whichis journaled in 'i bearing 169 carried by the housing 150. 1When thetongs are moved to a position over the disk 167 and are opened torelease the Ware, the latter is removed laterally from between the tongsby' the rotation of the disk.V The disk 167 andthe shaft 168 are rotatedby means of a gear wheel 170 which is fixed to the lower end of theshaft 168 and is driven by a gear wheel 171 carried by the shaft 61 ofthe transferring mechanism (Figs. 2,13 and' 9). A suitable conveyormechanism 173 is arranged ladjacent, to the disk 167, to which the Wareis deflected by means of a suitably disposed guide bar 174 (Fig. 2).'coming prematurely displaced from the disk 167 by means of a coactingguard bar 175.

The Ware is prevented from bel' llhe operation of the transferringmechanism may be discontinued at any time, either simultaneouslywith'that of the shaping Vmachine or independently thereot','by means ofthemechanism shown in Figs. 5, 6, 19, 20

A rock shaft 176 extends transversely along one side oi the easing 58and is mounted in bearings 177 carried by one oi the side walls thereotl(Figs. 5 and 6). lever 178 is lixed to one extremity of the shol't 176and extends to a position beneath the trcadle lever 113 ot' the shapingmachine (Figs. 1 and 21). The outer end of the lever 17 8 is yieldablyheld upwardly for engagement with the lever 43 by a spring 179 which isconnected at its upper end to a fixed portion of the machine, .notshown. An arm 186 is hired,u to the shaft 176 and is pivotally connectedto one end of a latch bnr fixed to the shaft 176 and is cngagcable by adog 186 which is pivotally mounted on a side wall o l the casing 58.

When the shaping machine is in operation. the treadlc lever oscillatesvertically A treadle under the action of the'cam 29 and the bell '-1crank lever 32 (Fig. 1), moving the lrcadhl 178 with it and etl'ecting acorrcspomfling ofcillation of the rock shaft 176 and latch arm 180 andmoving the latch bar 181 to reciprocate into and out of the path ottravel i under normal conditions the linger portion 81 passes the latchbar 181 when the latter is in a retracted position. It', however, thetreadlea bar 178 is held in a depressed position, either by the treadlelever 43 or independently thereof, as will be hereinafterv explained,the latch bar 181 will be maintained in the path of the linger portion81, thus moving the other end of the pawl 75 out of the path of theshoulder7 6 ot the disk 7 7 at this portion of each rotation ot the wormgear 65 and'thereby leaving the disk 77 and shaft 61 stationary. Theoperation of all the parts which receive power from the drive shaft 61will consequently cease. T he mechanism is so timed that when the operVation thereof Vthus is discontinued, the various parts of the transferelements slop in positions of safety l'emote from the shaping1 machineand out of the path oi' travel oi lla` molds and their associated parts,lhrrehy `permitting the removal of ware b v hand ly of the operation ofthe-shaping machine,

tending intothe path-of the pawl 7 5, by

moving the dog 183 into engagement with" the arm 182, as illustrated inFigs. 5 and 6.

It is desirable, however, to, stop the avare transferring mechanism whenthe handle' 56 is operated ,to stop the operation of the shapingmachine, thereby effecting the stopping both of these machines byta.single manual operation. To -this end, the treadle 19, 20, 21), theextremityl of which is formed with an eye porti-on 185. .A link 186carrying an abutment 187'at its lowere end, eX-

tends loosely through the eye 185 and-'is` pivotally connected atitsupper endvto the crank arm .53` which actuates the lockbolt,v

mechanism ofv the shaping machine. Dur-V ing the normal operation ofthemachine, lthe arm 53 extends`downwardly withthe link 186 dependingtherefrom, and the abutment 187 disposed out of the path of travel ofthe eye portion 185 of the arm 184. When the parts occupy this position,the arm 184 is free to oscillate, under the action of thetreadle-lever43 and spring-17 9, with the eye portion y185 slidingfreely along the link 1-86. Ifhowever, the lever 56 of the latch bolt.mechanismis moved to the position shown in full lines in Figs. 19, 20and 21, to push out the lock bolt and discontinue'the operation of theshaping machine,- the arm 5-3wi1-l be swung upwardly .and raise the link186.

' The raising of the link 186 elevates the abutment 187 against the eye185 and-maintains the arms 184 -in a raised position with the latch barl181 disposed in the path of the pawl 7 5, thereby discontinuing the`openation of the transfer `mechanism simultaneously with that ofthe-.shaping machine.'-

- The various elements of thetransferring mechanlsm are prevented fromoverrunning when they are disconnected from their source of power, bymeans of a `brake band 188 which partially surrounds the 4periphery7 [ofthe cam 87 I(Figs. 8 and 9). One end of this band-'is fixed to thecasingat 189 and the other end thereof is adjustably secured to the casing at190.4 In order to insure that the parts will come to rest intheir-'proper position, a' spring pressed cletent 191 is provided whichis slidably mounted in a guidewa'y 192-carried by the casing 58 andqispro-v vided witha roller 193 for yield'able engagement with a recess 194formed in the periphery of thecam 87. g l

f The shapingmachine is e uipped with a pneumaticallly controlled stopdevice which is operated by the transfer mechanism in the event that anabnormal strainisenco}1ntered through the failure of a'mold to open vorthe ware becoming lodged therein, (Figs..1, 22 and 23); This device cat)mprisesa rod 195 .which is mounted for vertical sliding movement inbearings 196 and 197 carried by a. bracket member 198. The bracket 198is mounted on a fixed portion of the shaping.

machineand in a position that will permit. the rod 195 to be projectedinto the path ofv movement of the arm 46 of Vthe bell crank lever 32(Figfl). y

The bearing 196 constitutesa casing for a spring -199 which surroundsthe rod 195 and bearsagainst-a collar 2004carried thereby (Fig. 23,).Anarm 201'ha61ing a hub portion 202 is fixed to the rod 195.intermediate of its bearings, and .is provided with an .ad-

justing screw 203 (Fig. 22). During the normal operation of the machine,the rod 195 is maintained ina retracted position against and is providedwith a shoulder 207 for en'- ,'Jfageme-it with a shoulder 208 formed onthe latch 204.` The latch-205 is, in turn, maintained in operativeposition by a plunger 209 carried by a diaphragm 210. The diaphragm 210is disposed within an air chamber 211 in the bracket 198 and is flexedout- Wardly by airpressure supplied from apipe 212 through reconnectingpipe 213. AnfeXl haust pipe 214 also communicates with the chamber 211and leads to a bleeder valve 215 mounted on'the transfe1 mechanism(Figs: 19 and 10).- f j i The valve 215 is ycarried by a stem .216 andis normally'maintained in a closed/posi! tion by a spring 217, The valvestem 216 eX- tends through the wall of the casing 58 and terminatesat apoint adjacent to the outer end of a rod 218 whichis carried by thedetent 116. In the event that an overload is encountered the detent 116will be forced out x of engagement with its notch 117 to disconneet thelevers and 113, as has been pre.- viously described (Fig. 9).' Thismovement of the detent 116 will force the rod 218 carried thereby. intoengagement with the valve stem 2.16 and open the valve 215. The

uff

opening of the valve 215 will relieve the air pressure in t-he pipe 214and the chamber latch 205 out of engagement therewith. The

release 0f thejlatch 204 permits the rod 1 95 to be raised by the spring199 into the path of the arm 46.' The lever 32 will therefor bemaintained in a position with the bolt 23 ont of engagement with thetable as long as the stop device is reset byineans of a levell 219 7(Figs. l, 22 and 23) which is pivoted to the vrod 195 is inthe path ofthe arm 461 The-- bracket 1,98 at 220 and which bears against the collar200 of the rod 195. One end of the lever 219 is engaged by a lever 221which is lixed to a shaft 222 provided with an operating handle 223. A

Then the operation of the shaping machine is discontinued, it isnecessary that the supply of glass thereto from the feeding mechanismshall be also discontinued. In order, therefore, to accomplish this end,the machine is preferably equipped with a pneumatic feeding device (Fig.24) such as that disclosed in my Patent No. 1,466,367. This feedercomprises a forehearth 22e provided with an orifice 225 through whichthe molten glass emerges for severance into individual gobs or moldcharges by a pair of shear blades 226. A laterally movable guide 227 isdisposed beneath the orifice 225 and directs the mold charges afterseverance into a vertically movable trough 228 which delivers them tothe molds of thc shaping machine. The upper end ofthe trough 22S iscarried by a bracket-'229 which is provided with a deflecting guide 230and a pair of forwardly extending arms 231. `The arms 231 aie secured tothe opposite ends of a piston rod 232 which extends entirely through anair cylinder 233 and is provided with the usual piston 234. The cylinder233 is fixed to a bracket 235" and may be supplied with air underpressure from a pipe 236 which coinmunicates with the interior of avalve casing 237 provided on the bracket 19S of the safety stop device(Fig. 22)'. A pipe 238 establishes communication between the valvecasing 237 and the pressure supply pipe 212 (Fig. l). vCommunicationbetween the pipes 236 and 238 is interrupted, during the normaloperation of the machine, by a valve member 239 disposed withinthechamber 236 and provided witli a depending valve stem 240. Then therod 195 is elevated into the path of the arm 46 to discontinue theoperation of the shaping machine, as previously explained, the screw 203on the arm 201 (Fig. 22) will raise the lower end of the valve stem 240and open the valve 239 thereby admitting air under pressure intothe-,cylinder 233 of the feeding device and raising the trough 228 tothe position shown in dotted lines in Fig.

24. In this position the trough is carried' out of alignment with theguide 227 and the defiecting guide 230 is brought into a position inwhich it will deflect the mold charges delivered from tlie feeder into acullet pit.

- not shown. As soon, however, as therod 195 is lowered, in order tocontinue the operation of the shaping machine, the arm 201 is loweredpermitting the valve 239 to close, thereby cutting off the supply ofcompressed air to the cylinder 233. The trough 228 may then return toits normal feeding position under the action` of gravity, the air in thecylinder 223 escaping through a relatively small bleeding aperture 241,which is provided in the piston 234. A valve 242 may be provided in thepipe 236 by means of which the supply of air to the cylinder 233 may becut off independently of the automatic cutoff heretofore described.Vlien this valve is thus actuated, the air confined in the cylinder 233may escape to the atmosphere.

The trough 228 may be raised and lowered independently of the compressedair cylinder 233 by means of a handle 243 which is pivotally mounted onthe cylinder at 244 and which is provided with a cam lever 245 forengagement with a roller 24:6 carried by the bracket 229.

From the foregoing it will be apparent that a very efficient apparatusis provided in which the transfer mechanism not only opens the molds ofa shaping machine and elevates the ware therefrom. but.' controls orparticipates in the control of the operation of the entire shapingmachine, including the de-L livery of the mold charges thereto.

This take-out device is herein shown and described as being mounted inits own frame, separate from the shaping machine. This enables it to bemanufactured and handled as a separate unit, and to be readily removedand replaced, or transferred to another shapin gI machine. 0bviously,however, it may be incorporated in' the shaping machine as a unitarypart thereof.

The, particular embodiment of the' invention illustrated and describedhas been ses lected by way of example only, and it is to be understoodthat various modifications, arrangements. and combinations may be em#plo'ved in fulfilling the'spirit of the vinvention as defined in theclaims.'
